Sure. The question will be coming up eventually, though, and I think the options on the packaging side are: 1) Disable jit completely 2) Compile --with-llvm, but disable jit in the config by default 3) Compile --with-llvm, but disable jit for older llvm versions 4) Enable jit everywhere where llvm >= 3.9 is available Option 4 is what the Debian packages implement now, but it might make sense to go to 2 or 3 for PG11 (only).
